Agreed

Brought my brother over to listen after purchasing mine(as I always do when I buy new gear), and all he said was "Man, thats almost toooo loud." Then I went to Reference. He'll never be the same lol.

I was amazed when I went from -1 to +4 on the AVR, the intensity seemed to double and this is where it hit 127db. I had no idea the system could get that loud, I half expected something to blow, it handled it no problem.

I want to try max spl on mine too but don't know were the voice coils are going to start frying.

Previously, got my single DLS-5000R Velodyne and other 5 channels to hit 124db but have not tried it with the MFW and Velo yet.

Besides the obvious, what should I look for ?

I just listen for distortion, at that level it's easy to tell when things start to break up. At 127db it still sounded clean but the music I was playing wasn't what I would call fast.

I have heard others crank the system up to badly distorting levels and for some reason they think it sounds great, I'm guessing some people can't tell although I can't grasp how since to me it's so obvious. But then some people can't tell when speakers are out of phase either, and all of them seem to work for stereo stores.

So this should hold up until this gets resolved.

Does this scenario look familiar to you, KH?

Unbelievable! If I wanted to work on subs I would have gone DIY, that's just not right. I never had to work on any sub I ever owned, and I would not expect to. Granted it's easier to do a field replacement of an amp or driver, but I wouldn't let the seller get away with that. IMO warranty repairs should be handled by the seller, and they should pay for shipping to boot. I bet if everyone did that QC would improve a lot... just saying!

I hear ya, however sending the subs back to AV123 isn't much of a benefit to either seller or customer. Time wise it makes more sense to send the parts and let the customer replace them.

Typically however the repair works the first time. For MFW # 1 this was the case, my luck for MFW # 2 hasn't been so good but we're working on it. Hopefully the next one is the charm. We'll see.

I'll agree with you there. However, the downside is all the labor time you've involved. This has meant:

1) Less time to spend using the sub

2) Less time to spend with family

3) Less time to enjoy other hobbies that you may partake in

4) Less time to just relax after a hard day's word

Yet, VA321 will never reimburse you for any of your time. Though, I think $30 an hour would be sufficient. An hour should be able to cover removing the old amp, installing the new one along with any recalibration of the amp that may be required.

I manufacture for a living, I am not working for free! Believe me, I was compensated for my time. Kyle was very good to me about that. Although I was banned from their forum later, so I guess he is done with me.

From that day on (repair day), I have always said to consider the MFW-15 a DIY sub.

What type of compensation can one expect to get?

I received two Ultralink 4 meter RCA cables ($80). And since it was a cold solder joint that caused the failure (speaker terminal), I asked that another driver be sent out with the wire soldered onto the terminals correctly. This means I have a back up driver. Yes, I could have fixed the cold joint, but... now I have a spare driver.

You can ship the entire subwoofer back per warranty terms. However, does everyone save the original packaging? One problem is you have to pay for shipping both ways. If the subwoofer is smashed / damaged during this extra shipping, it's your problem.

It probably takes less time and effort to swap out an amp than it does to packup a subwoofer properly for shipping.

I have been thinking about getting a second MFW-15 to go with the one I've owned since October of 2008. After reading this thread I've decided not to.

I guess I am one of the lucky ones who hasn't had a problem with the original amp. How do I know what version amp I have? I know it isn't a V3!
Tmac30's Avatar Tmac30 04:17 PM 06-09-2010
hey beeker. Look at the amp on the back of the sub. The one I have has a white sticker on the amp which is a V2 amp. The original amps did not have a sticker on them I don't think.

The 1st generation amp has two white stickers.One says tested,The other is the serial number.

The V3 just recently came out. If you've had yours since Oct 2008 without replacement it's V1. The V2 started shipping around July 2009.

That makes sense. I must have the V1. I guess I am lucky that I haven't had a problem. I did have the hum that was corrected but moving the wires around. I also have the infamous ground loop hum but the cheater plug fixed that.

What is considered to be the best amp?

I checked when I first installed the MFW-15 and it draws close to 30 watts even in standby. It also stays warm to to the touch in standby. I've never checked it after a long work out to see how hot it gets.

For those interested Kevin at Motor City Audio announced the Turbo upgrade kit is available. This kit should put this sub in elite group of subs will have to wait for posted results of course.

This isn't true, some may have but neither of my gen 1 MFW's had any stickers on them. I had no idea what serial number either was. All V2's have a serial number sticker.

Some folks might find it of interest that after relentlessly posting about the MFW and Turbo, you have decided NOT to go with the Turbo, but rather buy one or more of the subs from Craig Chases' Tweak City Audio. I forget if you are getting the 18.1 or 18.2 and whether you are getting single or doubles.

The CS 18.2 is an 800 watt dual 18 inch sealed sub selling for $1275 plus shipping. 40 inches high by 20 wide by 20 deep.
